Generations of Computers
First Generation Of Computer
First-generation computers, which were created between the 1940s and 1950s, represented the start of the computers. These computers employed vacuum tubes for circuitry and magnetic drums for storage. First Generation Computers were too bulky and large that they needed a full room and consumed a lot of electricity.
1. First Generation of Computers(1940 – 1956):
The period from 1940-1956 was the period of first-generation computers. They are basically based on vacuum tubes, and vacuum tubes are used as the basic components for memory and circuitry for CPU (Central Processing Unit).
2. Second Generation of Computers (1957 – 1963):
The second generation of computers consists of two types of devices transistors and magnetic core. e.g., IBM 1401
3. Third Generation of Computers(1964 – 1971):
Jack Kilby invented the Integrated Circuit. This Integrated Circuit replaced the use of transistors in the third generation of computers. Integrated Circuits itself consists of many transistors, capacitors, and resistors and due to this third-generation computers are smaller in size, efficient, and more reliable. For e.g., CDC 1700
4. Fourth Generation of Computers(1972 onward):
VLSI (Very Large Scale Integrated) Circuit or they are also known as microprocessors are used in Fourth generation computers. Microprocessor chip is made up of thousands of Integrated Circuits build on a single silicon chip. The use of Personal Computer(PCs) increased in this generation and First Personal Computer (PC) was developed by IBM. For e.g., Apple
5. Fifth Generation of Computers(Present and Future):
It is based on Artificial intelligence (AI) software. Artificial intelligence describes the medium and way of making computers like humans, the way human think, the way humans act, etc. and this is an emerging branch and has all the scopes for research work too. For e.g., PARAM 1
